More speculations
Spoiler for about Aono and Yorito:
I wonder if Aono also put some of her own emotions into Yorito as Aono before Yorito paper golem was much more livelier and emotional, while the current one seems to be devoid of emotions for much of the times. Maybe she actually put some essence of her own soul into Yorito to give it its own soul. According to Catholic Theology, soul can be nurtured and grown, just like you would nurture your mind and expand them. May be similar story with Aono, thus if she was given more time, she would eventually return closer to her original self before Yorito golem, while Yorito's mind and soul would go their own way and grow into normal adult? That still would be somewhat tragic as this Yorito golem would become an adult trapped in young teenager body, which is not always a good thing, or maybe Aono can manipulate things enough to give it adult appearance. Ah. doesn't matter any more as, like Yuji in Shana, Yorito knows he is a 'torch'.
By the way, the next week preview with Koyori was rather disturbing.
